The cause of lupus remains unknown, but there is solid evidence that genetics, epigenetics (changes in chromosomes that affect gene activity), environmental factors, viruses and infections play a role. Further study of these variables is expected to improve our understanding of causes, which should lead to improved diagnosis, prognosis, prevention, and treatment.


The modern period, beginning in 1920, saw major developments in research into the cause and treatment of discoid and systemic lupus. Research conducted in the 1920s and 1930s led to the first detailed pathologic descriptions of lupus and demonstrated how the disease affected the kidney, heart, and lung tissue.[115] A major breakthrough was made in 1948 with the discovery of the LE cell (the lupus erythematosus cell—a misnomer, as it occurs with other diseases as well). Discovered by a team of researchers at the Mayo Clinic, they discovered that the white blood cells contained the nucleus of another cell that was pushing against the white's cell proper nucleus.[116] Noting that the invading nucleus was coated with antibody that allowed it to be ingested by a phagocytic or scavenger cell, they named the antibody that causes one cell to ingest another the LE factor and the two nuclei cell result in the LE cell.[117] The LE cell, it was determined, was a part of an anti-nuclear antibody (ANA) reaction; the body produces antibodies against its own tissue. This discovery led to one of the first definitive tests for lupus since LE cells are found in approximately 60% of all people diagnosed with lupus.[118] The LE cell test is rarely performed as a definitive lupus test today as LE cells do not always occur in people with SLE and can occur in individuals with other autoimmune diseases. Their presence can be helpful in establishing a diagnosis but no longer indicates a definitive SLE diagnosis.
Lupus nephritis is managed with a combination of glucocorticoids [130] and immunosuppressive agents to slow the progression to end-stage renal disease (ESRD), along with maintaining normal blood pressure levels (ie, target of ≤130/80 mm Hg). [61, 96] In general, individuals with class I or II lupus nephritis do not need management with immunosuppression. [96]

A healthy diet is important in general, but perhaps even more so for the roughly 1 million Americans and 3 million people worldwide who suffer from systemic lupus erythematosus (SLE).1 Because of the multifaceted challenges presented by the disease, consuming adequate amounts of the right nutrients — and limiting others — can help relieve symptoms and improve outcomes.


It is estimated that more than 1.5 million Americans have lupus. African American women are three times more likely than white women to have it. Hispanic, Asian and Native American women also have a higher incidence of lupus. People of all ages, races and sexes can get lupus, but 9 out of 10 adults with the disease are women between the ages of 15 and 45.
Steroids . Steroid creams can be applied directly to rashes. The use of creams is usually safe and effective, especially for mild rashes. The use of steroid creams or tablets in low doses can be effective for mild or moderate features of lupus. Steroids also can be used in higher doses when internal organs are threatened. Unfortunately, high doses also are most likely to produce side effects.

Whole foods, especially the kinds high in probiotics, antioxidants and prebiotic fiber, can lower inflammation by increasing “good bacteria” in the gut, which help with absorption and defending against toxins or bad bacteria. High-antioxidant foods also have anti-aging effects even for those without lupus or another immune disorder because they fight free radical damage that degenerates cells and tissues.

A biopsy is a procedure that removes a small piece of living tissue from your body. The tissue is examined with a microscope for signs of damage or disease. Biopsies can be done on all parts of the body. A biopsy is the only test that can tell for sure if a suspicious area is cancer. But biopsies are performed for many other reasons too. There are different ways to do a biopsy. A needle biopsy removes tissue with a needle passed through your skin to the site of the problem. Other kinds of biopsies require surgery.

Hormonal mechanisms could explain the increased incidence of SLE in females. The onset of SLE could be attributed to the elevated hydroxylation of estrogen and the abnormally decreased levels of androgens in females. In addition, differences in GnRH signalling have also shown to contribute to the onset of SLE. While females are more likely to relapse than males, the intensity of these relapses is the same for both sexes.[12]

People with SLE need more rest during periods of active disease. Researchers have reported that poor sleep quality was a significant factor in developing fatigue in people with SLE. These reports emphasize the importance for people and physicians to address sleep quality and the effect of underlying depression, lack of exercise, and self-care coping strategies on overall health. During these periods, carefully prescribed exercise is still important to maintain muscle tone and range of motion in the joints.
Blood clots are seen with increased frequency in lupus. Clots often occur in the legs (a vein clot, called deep venous thrombosis), lungs (a lung clot, called pulmonary embolus), or brain (stroke). Blood clots that develop in lupus patients may be associated with the production of antiphospholipid antibodies. These antibodies are abnormal proteins that may increase the tendency of the blood to clot.
The panel judged the effect of extended AC as a large benefit, reducing VTD with increase in bleeding risk as a moderate harm. For the comparisons of different AC intensities, the panel decided to use the evidence from observational studies because it judged that it probably better reflects reality given that the randomised controlled trials (RCT) are severely flawed (indirectness of intervention as most patients did not reach the INR >3 goal). They judged the reduction in VTD as a large benefit and the bleeding increase as a large harm. Hence, the panel considered that the balance could favour the intervention only when the risk of VTD recurrence is particularly high.
Genetics Doctors and researchers believe a genetic predisposition may contribute to the development of lupus, says Kaplan. Dozens of genetic variations have been found to be associated with the disease, affecting who gets it and how severe those cases are, according to the Lupus Foundation of America. That means the disease is hereditary, making parents more likely to pass it to their children. But just because you are genetically predisposed to the condition, doesn’t necessarily mean you’ll get it.
Research has demonstrated evidence that a key enzyme's failure to dispose of dying cells may contribute the development of systemic lupus erythematosus. The enzyme, DNase1, normally eliminates what is called "garbage DNA" and other cellular debris by chopping them into tiny fragments for easier disposal. Researchers turned off the DNase1 gene in mice. The mice appeared healthy at birth, but after six to eight months, the majority of mice without DNase1 showed signs of systemic lupus erythematosus. Thus, a genetic mutation in a gene that could disrupt the body's cellular waste disposal may be involved in the initiation of systemic lupus erythematosus.
The diagnosis of lupus is best made by an experienced clinician who fully understands the disease and other diseases with similar features that can mimic lupus. The diagnosis is made when a patient has several features of the disease (including symptoms, findings on examination and blood test abnormalities). The American College of Rheumatology has devised criteria to assist clinicians in making the correct diagnosis of lupus.

Inflammation of the lining surrounding the lungs, or pleuritis, can occur in people with lupus. This can cause symptoms such as chest pain and shortness of breath, says Luk. The pain can worsen when taking a deep breath, sneezing, coughing, or laughing. (18) Pleural effusion, or fluid around the heart and lungs, may also develop and can cause shortness of breath or chest pain, says Caricchio.
A general, imprecise, colloquial, and somewhat old-fashioned term for acute and chronic conditions marked by inflammation, muscle soreness and stiffness, and pain in joints and associated structures. It includes inflammatory arthritis (infectious, rheumatoid, gouty), arthritis due to rheumatic fever or trauma, degenerative joint disease, neurogenic arthropathy, hydroarthrosis, myositis, bursitis, and fibromyalgia.
Similarly, a phase III trial of 819 SLE patients who were positive for either antinuclear antibody or anti–double-stranded DNA at baseline screening found that IV belimumab at 10 mg/kg plus standard therapy resulted in a significantly greater SRI score (43.2%) than placebo (33.5%) at 1 year (those who received belimumab 1 mg/kg plus standard therapy had a 40.6% response rate). [118] Overall, the addition of belimumab to standard therapy reduced SLE disease activity and severe flares, and the medication was well tolerated. [118]
The complement system is the name of a group of blood proteins that help fight infection. Complement levels, as the name implies, measure the amount and/or activity of those proteins. Working within the immune system, the proteins also play a role in the development of inflammation. In some forms of lupus, complement proteins are consumed (used up) by the autoimmune response. A decrease in complement levels can point toward lupus nephritis, lupus nephritis, kidney inflammation. Normalization of complement levels can indicate a favorable response to treatment.
Painless passage of blood or protein in the urine may often be the only presenting sign of kidney involvement. Acute or chronic renal impairment may develop with lupus nephritis, leading to acute or end-stage kidney failure. Because of early recognition and management of SLE, end-stage renal failure occurs in less than 5%[27][28] of cases; except in the black population, where the risk is many times higher.
Studies have shown that lupus multiplies a woman’s risk for osteoporosis five times4 – an alarming figure, no doubt. Osteoporosis is a condition where bone density decreases, leading to an increased risk of skeletal fracture at older age. Like lupus, osteoporosis has no cure, so it's a condition better prevented  than treated, especially for women.
Avoiding sunlight in SLE is critical, since sunlight is known to exacerbate skin manifestations of the disease. Avoiding activities which induce fatigue is also important, since those with SLE fatigue easily and it can debilitating. These two problems can lead to people becoming housebound for long periods of time. Drugs unrelated to SLE should be prescribed only when known not to exacerbate the disease. Occupational exposure to silica, pesticides, and mercury can also worsen the disease.[60]
A diet high in folic acid, such as found in leafy green vegetables, fruits, and fortified breads and cereals, or a folic acid supplement is important if you are taking methotrexate (Rheumatrex). For nausea caused by medications, eat small frequent meals and foods that are easy to digest. Try dry cereals, breads, and crackers. Also avoid greasy, spicy, and acidic foods.
Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines.
To unravel which people with positive ANA tests actually have lupus, additional blood work can be done. Doctors look for other potentially troublesome antibodies, so they will test for anti-double-stranded DNA and anti-Smith antibodies. These tests are less likely to be positive unless a patient truly has lupus. However, a person who has negative test results could still have lupus, even though this is not so in the case of ANA tests.

Patients of African-American or African descent did not show significant responses to belimumab in phase III post-hoc analysis, but those studies were not powered to assess for this effect; in a phase II trial, blacks had a greater treatment response. These results indicate that the benefits of belimumab in SLE patients remain inconclusive and that further investigation is needed. Patients with severe active lupus nephritis or CNS lupus or patients previously treated with other biologics or cyclophosphamide have been excluded from participation in early trials.
“There are no foods that cause lupus and no foods that cure it, but eating a well-balanced diet may help combat some of the side effects of medications, as well as alleviate symptoms of the disease,” said Laura Gibofsky, MS, RD, CSP, CDN, a clinical nutritionist at the Hospital for Special Surgery in New York, New York. First, the “Western diet,” consisting of an excess of fatty, salty, sugary foods, has been implicated in autoimmune diseases overall.2 Proper nutrition can also help improve the risk of comorbid diseases that commonly affect patients with SLE.
Inflammation of blood vessels (vasculitis) that supply oxygen to tissues can cause isolated injury to a nerve, the skin, or an internal organ. The blood vessels are composed of arteries that pass oxygen-rich blood to the tissues of the body and veins that return oxygen-depleted blood from the tissues to the lungs. Vasculitis is characterized by inflammation with damage to the walls of various blood vessels. The damage blocks the circulation of blood through the vessels and can cause injury to the tissues that are supplied with oxygen by these vessels.

Recent research has found an association between certain people with lupus (especially those with lupus nephritis) and an impairment in degrading neutrophil extracellular traps (NETs). These were due to DNAse1 inhibiting factors, or NET protecting factors in people's serum, rather than abnormalities in the DNAse1 itself.[65] DNAse1 mutations in lupus have so far only been found in some Japanese cohorts.[66]


Corticosteroids may also be used to get rid of lupus flares, or the appearance of symptoms after a period of remission, says Francis Luk, MD, an assistant professor of rheumatology and immunology at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina. “Depending on severity and type of flare and how many flares the patient has recently experienced, rheumatologists may adjust medications,” he adds.
